Lead in

The DEV-40 is a product which is intended to offer PIC micro controller enthusiasts a development platform. While many other options exist, many PIC users found its versatility and cost effectiveness a valid reason to change over. However, PIC based products and systems continue to offer a strong alternative.

NOTE: The ProtoDev-40 was originally released under our previous company ZarDynamix, and we continuing the availability under HavenTechnik.

Introduction

The ProtoDev-40 is a member of the BluBery family and offers form factor compatibility across the range of development PCBs. The 16F and 18F families share a similar pinout and this enables products and systems to be PIN compatiable, allowing for code to be deployed from a smaller device in pin count and features to a bigger device such as the PIC18F45K22.
The PIC18F45K22, which is SMT mounted onto the PCB offers a number of advanced features including dual comports, comparators, and so on. See the features set below:

^{NOTE: The feaures below are a subset, please refer to the Microchip datasheet for more details.}

Down to Code

Shown below is a simple code sample for a Hello World project example. The code demonstartes how to configure the PIC and flash an LED.


                /* It's That Easy Series - PIC18F45K22 */

                    void ConfigureDevice()
                    {
                        // Peripherals you don’t need
                        ANSELA = 0x00;
                        ANSELB = 0x00;
                        ANSELC = 0x00;
                        
                        // Inputs and Outputs
                        TRISB = 0b11111110;
                        // Initial PIN Configuration
                        LATB.B0 = 0;
                        }
                    
                        Flash_LED()
                        {
                        LATB.B0 = LATB.B0^1;
                        Delay_MS(500);
                        }
                    
                        void WhatToDo()
                        {
                        Flash_LED();
                        }
                    
                        void main() {
                    
                        ConfigureDevice();
                    
                        while(1)
                        {
                            WhatToDo();
                        }
                    }

Why use the ProtoDev-40. . .

The ProtoDev-40 utilizes one of Microchip's powerfull, energy efficient and extensbible devices. Prepopulated on the RADIX, it's a power up and play solution capable of running from a USB cable. The Device itself offers many itegrated peripherals namely: USART, I2C, SPI, PWM, CCP timers and so on. That's allot of techno jargon, but it equates to a compact purchase with many open doors for ongoing development; the device will allow you to grow your project to its full potential.
